What Is A Grinder? How Should The Daily Maintenance of The Grinder Be Carried Out?

Grinding machines produce flat, cylindrical, and other surfaces through high-speed rotating abrasive wheels. Grinding is a means of giving a more accurate finish to a part already machined but is also a machining process in its own right. The main types of machine are the ‘surface grinding machine’ for flat surfaces; and the ‘cylindrical grinding machine’ for cylindrical surfaces. More complex shapes are produced by shaped wheels called ‘contour grinding wheels’. ‘Bench’ and ‘pedestal’ grinders are used for tool sharpening, etc.

All About Engine Valves

Engine Valve Motion The motion of the engine valves is driven by the camshaft of the engine, which contains a series of lobes or cams that serve to create linear motion of the valve from the rotation of the camshaft. The number of cam lobes on the camshaft is equal to the number of valves in the engine. When the camshaft is in the cylinder head, the engine is called an overhead cam (OHC) design; when the camshaft is in the engine block, the engine is called an overhead valve (OHV) design.
